People tend to call the pain in their side that arises during exercise a “side stitch.” Did you know there is a medical term for this? Exercise-related transient abdominal pain, or ETAP, is what that side pain while you’re exercising is technically called. Despite a few studies on this, the causes prove to be too numerous and a standardized remedy cannot be found for all the causes. The best advice is to run down the possible causes for your situation and try to correct them. A few that might work are: not eating soon before your workout, check your posture during the activity, make sure you’re hydrated, and/or don’t drink too much before activity. It can be incredibly frustrating, but if the pain does not go away when your activity ends, check in with a professional.
